NOTES:

1.Fan performance is based on dry coils, economizer, roof curb, cabinet losses, and clean 2-in. filters.

2.Conversion — Bhp to watts:

Motor Efficiency

3.Variable Air Volume units will operate down to 70 cfm/ton in the cooling mode. Performance at 70 cfm/ton is limited to unloaded operation and may be additionally limited by edb (entering dry bulb) and ewb (entering wet bulb) conditions.
